评价了偏氟乙烯（VDF）低聚物作为新型触觉传感器的医用压电效应。VDF低聚物是一种新的物质，其VDF单元数量较少，分子量低于聚偏氟乙烯（PVDF）;在有机铁电体中，它具有最大的已报道的反射极化。在这项工作中，基于这种材料的原型传感器设备的性能进行了评估。发现VDF低聚物的压电系数大于P（VDF/TrFE）共聚物的压电系数;由VDF低聚物组成的膜薄且均匀。根据实验结果，讨论了VDF齐聚物在医用触觉传感器中的可能应用。这项研究证实，VDF低聚物是一种很有前途的铁电材料，用于触觉传感器。(C)2008 Elsevier B. V.保留所有权利。
The piezoelectric effect of vinylidene fluoride (VDF) oligomer was evaluated with respect to its medical use as a new tactile sensor. VDF oligomer is a new substance that has a smaller number of VDF units and a lower molecular weight than poly(vinylidene fluoride) (PVDF); among the organic ferroelectrics, it has the largest reported remanent polarization. In this work, the performance of a prototype sensor device based on this material was evaluated. The piezoelectric coefficient of VDF oligomer was found to be greater than that of P(VDF/TrFE) copolymer; a film composed of VDF oligomer was thin and uniform. Based on the experimental results, possible applications of VDF oligomer in medical tactile sensors are discussed. This study confirms that VDF oligomer is a promising ferroelectric material for use in tactile sensors. (C) 2008 Elsevier B.V. All rights reserved.
